IPC: B62D11/08
Filed: 1936-02-11
Abstract: 465,303. Steering endless - track machines by driving-gearing. EVANS, W. E. (Demag Akt.-Ges.) Feb. 11, 1936, No. 4120. [Class 79 (ii)] In an endless-track excavator or crane steered by de-clutching and braking either track, the clutch and brake of at least one track are controlled by a transverse steering rod 5 which passes through the track to the outer side of the machine, so that it can be actuated by a man walking alongside. The rod has one position in which the clutch is engaged and the brake free, and another position in which the clutch is disengaged and the brake applied, and is so arranged that if the man pulls it to his right the machine steers to the right. The excavator body a is mounted on a turntable and the tracks are driven from an engine b through a shaft f concentric with the turntable pivot and a transverse shaft 18. Each track 1 has a sprocket 3 which can be driven from the shaft 18 through a clutch 23, 24 and a sprocket 15. The clutch member 23 is operated by the steering rod 5 through a lever 6 pivoted at 6a and a slidable collar 17 connected by a central rod 20 to the clutch member. The lever 6 has an arm 9 connected to a lever 10 which operates a brake band 11 acting on a drum 14 on the sprocket 15, the arrangement being such that in position I of the lever 6 the clutch is engaged, in position III the brake is applied, and in position II the clutch is disengaged and the brake is free. The clutch may be applied by a spring 22, and the rod 5 may have holding notches 26. The clutch and brake for the other track may be similarly controlled by a rod 5 or may be controlled from the driver's cab on the body a. When two steering rods 5 are provided they may project to either or both sides of the machine.

Abstract: 1,136,817. Photographic reflex cameras with roller blind shutters. EASTMAN KODAK CO. Feb.2, 1966 [Feb.5, 1965], No.4543/66. Heading G2A. Control mechanism for a single lens mirror reflex camera having a focal plane shutter and a mirror which returns to the viewing position immediately after exposure, comprises a first control slide 45 arranged to move the mirror 1 to and from the viewing position and to initiate operation of the shutter 33, 34; a second control slide 30 for resetting the mirror to the viewing position at the end of an exposure; and a lever coupling between the two control slides including a pair of levers 50, 47 mounted on a common shaft 48 for transmitting the resetting action of the second control slide to the mirror. One arm 50a of the lever 50 is actuable by a film winding and/or shutter locking and/or camera release mechanism, and the other arm 50b engageable by the second control slide. To effect film winding and/or shutter locking, a winding lever 18 is rotated in direction D. This motion causes the lever 50 to rotate clockwise (as seen in the Figure), thereby locking the arm 50a by a lever 56, tensioning a spring 49, displacing the slide 30 in the direction C and tensioning a spring 40. The shutter is tensioned (by means not shown) so that cam 38a takes up the dashed position shown. On making an exposure, a member 54 is depressed thus releasing the first slide 45 to move in the direction E, following the bell crank lever 47 which is pivoted clockwise under action of the spring 49. The mirror 1 is pivoted to its exposure position by means of a pin and slot connection 7b, 45a. Rotation of the lever 47 rotates a lever 53 allowing a diaphragm setting ring 25 to take up a preselected position. A pin 45c pivots a lever 36 out of the path of a toothed wheel 35 so that the first curtain 33 can run down for exposure. The second curtain 34 is released to run down by shutter timing means (not shown) and just before it has run down, the cam 38a pivots the lever 56 in the direction B. This frees the lever 50 to rotate under the action of the spring 40, thus pivoting the lever 47 to move the slide 45 upwards and return the mirror to its viewing position. The spring 40 also moves the slide 30 to the right, which movement rotates the diaphragm setting ring 25 until it is latched by the lever 53 in its fully open position. The camera is now once again in the initial position.
